specification of 1,301,204.` A, Application med March 5,

To all whom t 'may concern: r 1

Be it known that we, PAUL C. WARNER and ROBERT W. BLODGET, both citizens of the United States, and residents, respectively, of N ewRochelle, in the'county of Westchester and State of New York, and of the city of New York, borough'of Manhattanf,-1in the countyfand State of `New York, have `invented a new and Improved Ships Patch, of which the following-is a full, clear, and exact description. o a

Among `the` principal objects 4which the present inventionhas in view are: to provide means for closing ai gap or leak in the hull of a ship; to providemeans for readily disposing the-lling member in active service, `to accommodate leaksor apertures of unascertained size and shape; to provide patches of the lcharacter mentioned which are convenientlytransported; and to pro-- vide a patch adapted for augmenting the flotation of a ship.

Description.

As seen in the drawings, when the patch 11 is inactively disposed, it is preferably rolled to form "a bundle which is deposited on the trucks 12 and 13, as the case may be. Suitable lashings 141 or stakes 15 are provided for holding the bundles in position on the trucks. The trucks 12 and 13 are suit ably mounted for movement over the deck menaient.

of the ship, to launch the patch 11 into position to cover the holes or damaged area. The trucks 12, as seen in the drawings, are provided with caster wheels 16, which provide sufhcient flexibility of movement in the trucks to admit of the same being quickly moved to any desired part of the deck. As seen best in Fig. 2 of the drawings, Athe trucks 12 are disposed inactively in position adjacentthe center of the deck of the ship 17. The ship 17, when equipped with the trucks 12, is preferably provided with a central air supply pipe 18, which is connected with any suitable reservoir of air 33, or airpumping system having outlet valves 19, which are connected by means of flexible hose 20 with the patch or patches 11.

The patches 11 are fiat hollow bags, the Size of which is determined by experience, it being'intended that they shall cover the apertures usually caused by accident or by an attack, such as that inflicted by a torpedo. The patch is provided with a screw-threaded nipple 21, which is comiected by a sui-table coupling with a hose 20. An eyelet 22 is operatively connected by a cable 23, with a suitable windlass or winch 24:. The cable 23 serves to govern the lengthwise position of the patch when adjusting the same to the damage inflicted on the ships hull.

It will be understood that while there have been shown the patches with which the vessel is equipped, as being stowed on the deck thereof, they may be stowed between decks, it being intended to have them on deck only when ythe vessel is passing through some recognized dangerous area.

In Figs. 4. to 6, a modified form of the invention is shown, wherein the elongated truck 13 is provided with suitable carriages 25. The carriages 25 are supported by wheels 26, which track upon rails 27. One of the rails 27, as seen best in Fig. 4f of the drawings, is disposed beyond the side of the ships hull 17, and is there supported by a series of brackets. The other rail 27 is preferably disposed inboard or within the outer surface of the hull of *the ship. An overhanging guard rail 28 is disposed above each of the rails 27.

The carriages 25 are pivotally mounted at opposite ends of the truck 13 and the wheels of the said carriages are sufficiently closely related to permit the swinging of the carriages when 4the latter is moved around the curved portions of the rails 27, Where the'` same conform to the curvature of the stern of the ships'hull.

When using the modified form of theiinvention, the ship has a num-ber of stand pipes 29, to the valves of which is connected the hose pipe 31 with which each of the patches is furnished. The trucks 13 are drawn lengthwise of the ship and of the rai-ls 27 thereon, by cables 32, said cables being Wound on thewvinches 24 on the bowof` the ship. To use patches constructed and arranged as disclosed, the trucks 12 or 13 are placed'adjacent the bulwarks or bow of the ship. The cable 23 is made fast to the Winch 24 vand the patch 11 is thrown into the sea, the lashing 14 or stakes 15 having been removed as obstructions thereto. The patches 11 being constructed of relatively heavy material and completely deflated, have little or no buoyancy and therefore sink into the Water into Which they are thrust. The cables 23 arepaid out until the patch 11 passes over the hole or opening made in the side of the ship. vThe inrushing Water at this point carries the patch into the hole or opening. The patch is thenfraised by holding the cable 23,
